mdm-run - run a command in parallel with mdm-master
mdm-run command mdm-sync command
mdm-run annotates command as a candidate for parallel execution. If an mdm-master process is present (i.e., the environment variable MDM_CMD_SOCK is defined), mdm-run submits command to the mdm-master, and it exits when the master issues the command to an mdm-slave process (which may be connected to another terminal) for execution. mdm-sync runs command in place, but it coordinates with mdm-master to ensure that executing command does not interfere with commands that are currently executing in parallel. If there is no mdm-master process present (i.e., the environment variable MDM_CMD_SOCK is not defined), both mdm-run and mdm-sync simply run command as if you entered command all by itself. These programs are a part of the Middleman System (mdm).
Neither mdm-run nor mdm-sync accepts any options.
If there is no mdm-master process present, the exit status of mdm-run is the exit status of command. If an mdm-master process is present, the exit status is 0 if and only if command is successfully issued to an mdm-slave process for execution. The exit status of mdm-sync is always the exit status of command.
The mdm system uses the following environment variable for internal communication, and thus you should not try to set them yourself. MDM_CMD_SOCK mdm-run uses this environment variable to decide whether a mdm-master process is present.
See mdm.screen(1) for an example use of mdm-run.
